On strong Skolem starters

Adrián Vázquez-Ávila

In this note we present an alternative (simple) construction of cardioidal starters (strong and Skolem) for $Z_{q^{n}}$ , where $q \equiv 3$ (mod 8) is an odd prime number and…

On chromatic indices of finite affine spaces

Gabriela Araujo-Pardo, György Kiss, Christian Rubio-Montiel +1

The pseudoachromatic index of the finite affine space $AG (n, q),$ denoted by $ψ^{'} (AG (n, q)),$ is the the maximum number of colors in any complete line-coloring of $\…

Digraphs with at most one trivial critical ideal

Carlos A. Alfaro, Carlos E. Valencia, Adrián Vázquez-Ávila

Critical ideals generalize the critical group, Smith group and the characteristic polynomials of the adjacency and Laplacian matrices of a graph. We give a complete characterizatio…

On line colorings of finite projective spaces

Gabriela Araujo-Pardo, György Kiss, Christian Rubio-Montiel +1

In this paper, we prove lower and upper bounds on the achromatic and the pseudoachromatic indices of the $n$ -dimensional finite projective space of order $q$ .

On transversal and $2$ -packing numbers in straight line systems on $R^{2}$

Gabriela Araujo-Pardo, Amanda Montejano, Luis Montejano +1

A linear system is a pair $(X, F)$ where $F$ is a finite family of subsets on a ground set $X$ , and it satisfies that $∣ A \cap B ∣ \leq 1$ for every pair of distinc…

A note on the Erdös-Faber-Lovász Conjecture: quasigroups and complete digraphs

Gabriela Araujo-Pardo, Christian Rubio-Montiel, Adrian Vazquez-Avila

A decomposition of a simple graph $G$ is a pair $(G, P)$ where $P$ is a set of subgraphs of $G$ , which partitions the edges of $G$ in the sense that every edge of $G$ belongs to exa…
